Detailed Description

Port mapper responsible for re-mapping functionalities of GPIO pins.


DriverLib PMAP (Port Mapper) Operation


The port mapping controller allows the flexible and reconfigurable mapping of digital functions to port pins.

The port mapping controller features are:


Programming Example


The DriverLib package contains a variety of different code examples that demonstrate the usage of the PMAP module. These code examples are accessible under the examples/ folder of the SDK release as well as through TI Resource Explorer if using Code Composer Studio. These code examples provide a comprehensive list of use cases as well as practical applications involving each module.

Below is a very brief code example showing how to use the PMAP module to redirect the output of a TimerA CCR register.

First is the array configuration to remap the port:

Next is the call to the actual PMAP API that persists the configuration:
